Answer:

The function $f(x)=\sqrt{x-5}$

Step-by-step explanation:

The Range of any function is complete set of all possible resulting values of the dependent variable , after substituting the domain.

so, the function $f(x)=\sqrt{x-5}$ has range $f(x)$\geq$ -5$

This includes - 4 .

Hence, the function is $f(x)=\sqrt{x-5}$ .

y = -16x2 + 32x - 10 This parabola has x-intercepts, representing the times when the dolphin's height above water is feet.

Answer: This parabola has 0.3875 x-intercepts,
representing the times when the dolphin's height above water is 
0 feet.

The x-intercept is the point where the graph crosses the x-axis, which is when the value is y=0.
The calculation for y=0 would be
Y = -16x2 + 32x - 10
0 = -16x2 + 32x - 10
-8x2 + 16x - 5=0

-b +-√(b^2-4ac) /2a=
-16 +-√(16^2-4(-8)(-5)) /2(-8) =
-16+- √(256-160/ -16 =
-16+- √(96/ -16 =
-16+- 9.8/ -16 =
x1= 0.3875
x2= -1.6125

Margarita [4]

x-16+x=180

2x-16=180

2x=196

x=98 degrees

x-16= 82 degrees
